Application filed January 22, 1918. Serial No. 213,145.

I To all whom t may concern.'

Be it known that I, OLIVER CROSBY, a citizen of the United States, residing at St. Paul, county of Ramsey, State of Minnesota, have invented certain new and useful Improvements in Rope-Clips, of which the following is a specification.

The object of this invention is to provide a rope clip of such construction that any tendency toward slippage of the ropes or rods therein will cause the clip to grip them more securely, and the harder the pull on `.the cables or rods the more firmly they will be clamped by the clip.

The invention consists generally in various constructions and combinations, all as hereinafter described and particularly pointed out in the claims.

In the accompanying part of this specification, K

Figure 1 is a side view, partially7 in section, of a rope clip embodying my invention,

Fig. 2 is an end view of the same,

Fig. 8 is a vertical sectional view through the clip.

Fig. 4 is a sectional view of a modified construction.

In the drawing, 2 and 3 represent the lapping ends of the rope, secured together by the clip. 4 is a U-shaped bolt arrangedV to straddle the rope and 5 is a block having sockets therein to receive the ends of the bolt which extends below the block and are provided with clainping nuts 6 which, when tightened on the threaded ends of the bolt,

drawings forming clamp it firmly on the rope. 7 is a secondary Y block or shoe, having a concavek gripping surface 8 which has a comparatively long bearing on the rope or cable and opposing the gripping surface of the block 5. `This block 7 has a comparatively large opening 9 therein, in which the U-shaped bolt is mounted, and the lower walls of this open-V ing are curved, as at 10, to form cam surfaces on each side of the vertical axis of the bolt. The curved portion of the U-bolt normally rests in the centerof this opening andbetween the sam surfaces, but when the block is moved lenothwise upon slipping of the rope or rod, the bolt will slide and begin to climb one of the cam surfaces 10 and automatically increase the clamping or crushing strain of the clip on the rope.

The block 5 has upwardly extending portions 11 on opposite sides of the arms of the U-bolt and adjacentVY thereto, and when the rope begins to slip inthe clamp these portions of the block, engaging the arms of the U-bolt, will brace and support it and resist the tendency to bend the bolt.

The clip may be made in various sizes and the block 7 may be varied in length to increase or decrease its gripping surface and the length of the cam surfaces for engaging the U-bolt.

In Fig. 4 I have shown a modified construction which consists in providing a block 12 having a gripping surface 8 for the rope and a Wedge face 13 upon opposite sides of the U-bolt inclined inwardly and downwardly toward the center of the block and forming slightly inclined surfaces on which the Ul-bolt may slide to exert a further clamping action on the rope. Lugs 14 are preferably provided at the ends of the block extending above said inclined or wedge surfaces. l

f I claim as my invention:

1. A rope'clip comprising a U-bolt, a block slidably mounted on the arms thereof, nuts mounted on the threaded ends of said arms, a secondary block loosely mounted on the curved portion of said U-bolt and having a cam bearing surface for said curved portion, and on which cam bearing surface the curved portion of said bolt is free to slide when it is movedl by the slipping of the rope.

2. A rope clip comprising a U-shaped bolt, a block slidably mounted on the arms there- `of and clamping nuts mountedk on said arms opening, a, comparatively Wide gap being which said bolt is moved by the pulling formed on each side of said bolt between it strain on the rope to increase the pressure and the end Walls of said openingfor freeof said secondary block thereon. 10 dom of movement of said bolt in seid open- In witness whereof, I have hereunto set 5 ing, the bottom' of saidVV opening being my hand this 12th day' of January, 1918.
